Card Clamp is also a must for proximity and smart cards with electronics inside that would be damaged by slot punching.

Punching slots in ID cards causes several problems: it takes time, makes a weak spot in the card and compromises the protective overlay.

This new Clip-On Style Card Clamp makes slot punching a thing of the past thanks to gripper pads that securely hold your card to a pull strength of 9 lbs. The attached bulldog clip can swivel to attach to shirt pockets or collars. Since the drudgery of punching slots is eliminated, there are no more troubles like carpel tunnel claims and cards tearing out at the slot.
